The largest buy is $1 million and will air in the key battleground state of Ohio.
The RNC is spending nearly as much in North Carolina and Virginia - $938,000 and $915,000.
The remainder of the buy is split between New Hampshire, Colorado, Iowa, and Nevada.
An RNC official told CNN that "The RNC's fundraising success has allowed us to add an independent expenditure in addition to fully funding the ground game.
"That the committee's financial situation would be this strong would have been unimaginable when Chairman Priebus took over," the official continued.
Romney's campaign and the major super PAC supporting his candidacy - Restore Our Future - has bought millions in television time this month.
